基于文献计量学的城市洪涝灾害研究可视化知识图谱分析

Analysis of visual knowledge mapping of urban flood disaster research using bibliometrics

采用文献计量学方法系统梳理城市洪涝灾害的研究现状、研究热点和发展趋势,以期为城市洪涝灾害后续研究提供参考。基于2008—2019年Web of Science核心集数据库中城市洪涝灾害的相关文献,采用CiteSpace和SATI3.2软件对城市洪涝灾害相关文献的年度频次、发文期刊、发文机构、主题词共现、文献共被引以及研究前沿进行分析。结果表明:城市洪涝灾害的研究热点为气候变化和脆弱性等;城市洪涝灾害相关文献的出版数量与被引频次均呈增长趋势;从发文机构来看,发文机构主要集中在高校;影响、模型等主题词中心度较高,说明这些研究主题在城市洪涝灾害研究中处于重要地位。随着城市洪涝灾害的关注度逐渐上升,其研究视角趋向多元化,城市洪涝灾害的风险管理、应急管理和信息管理将是未来的研究重点。研究结果可为城市防洪减灾与应急管理提供理论参考。

Bibliometrics is used to systematically summarize the research status, research hotspots and trends of urban flood disaster, so as to provide reference for the follow-up research of urban flood disaster. Papers related to the urban flood disaster in Web of Science(WoS) in the period of 2008-2019 were selected. The CiteSpace and SATI3.2 software were used to analyze the annual frequency of papers, publishing journals analysis, research institutions analysis, co-occurring subject terms analysis, literature co-citation analysis and research frontier analysis. Results showed that the research hotspot on urban flood disaster focuses mainly on climate change and vulnerability. The number of published papers and cited papers has risen. From the perspective of the publishing institutions, publishing institutions are mainly concentrated in colleges and universities. Subject terms such as "impact" and "model" have a high degree of centrality, which show that these research topics play an important role in urban flood disaster research. With the increasing attention on urban flood disaster, the research perspectives of urban flood disaster are gradually enriched and diversified. The risk management, emergency management and information management of urban flood disaster will be the focus of future research. The results provide theoretical reference for urban flood control and disaster reduction and emergency management.
